Specification of Letters Patent.

Patented Oct. 24, 1905.

Application filed March 1l, 1904. dcrial No. 197,682.

To all whom, it 'nw/y concern:

Be it known that l, RICHARD Bownns, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Hoisting-Engines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to the accompanyingdrawings, and to numerals of reference marked thereon, which form a part of this specification.

This invention relates to hoisting-engines, and has for its objects to provide an attachment which can be utilized to turn the mast or boom of a derrick in either direction at will without reversing or otherwise affecting the normal motion of the machine; to provide for this purpose a single auxiliary drum and means for transmitting power to said drum to turn it in either direction; to secure a location of said auxiliary drum so as not to interfere with the normal working of the engine; to provide an attachment which can be applied to engines already built and which can be supplied with new engines or not, as desired; to secure simplicity and efficiency, and to obtain other advantages and results, some of which may be hereinafter referi ed to in connection with the description of the working parts.

The invention consists in the improved mastturning device for hoisting-engines and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like numerals of reference indicate corsponding parts in each of the several figures, Figure 1 is a plan of a hoisting-engine having my improved attachment applied thereto. Fig. 2 is an elevation of the same from the side opposite that at which the operator stands, and Fig. 3 is an elevation from the operators side of the machine.

ln said drawings, 2 2 indicate the side frames of a hoisting-engine adapted to be bolted, as shown, to skids 3, and upon these side frames is journaled a transverse drivingshaft 4, having at its ends outside the side frames crank-disks 5, with pins 6, adapted to receive the connecting-rods from the enginepistons. (Not shown.) Upon said shaft 4L is a small driving-gear 7, which meshes into a larger gear 8 upon the drum-shaft 9, also journaled in the said side :frames 2 2, whereby said drum-shaft is driven. Upon said drum-shaft 9 is the drum 10, normally loose and provided at one end with an internal friction-surface 11, adapted to engage a second friction 12 upon the gear 8, as is common. Any well-known means for forcing said drum against its driving-friction may be applied, as is usual in hoisting-engines, it not being thought necessary to illustrate the same in the drawings. In fact, all the parts described, it will be understood, are old and well known in the art, the drum 10 receiving the rope from a derrick to raise and lower loads.

My improved device, which l will next describe, is designed to provide an auxiliary drum to receive a rope from the bull-wheel upon the mast of the derrick, so that said mast or the derrick may be quickly and readily turned to swing the boom to any desired point, all as will be understood by one skilled in the art.

l have shown in the drawings auxiliary side frames 13 13, bolted to the skids 3 and the front end of the main side frames 2, and in which frames is journaled the transverse shaft 14 for my auxiliary drum 15. Obviously, however, the said auxiliary frames may be made in one piece with the main side frames, if desired, as well as the way they are shown.

For transmitting power to the auxiliary shaft 14 I provide upon said shaft outside the side frame 13 at one side of the engine, preferably that side farthest from the operator, a large wheel 16, recessed at its outer side and providing both internal and external gearsurfaces 17 13, respectively. Upon the extremity of said shaft 14, beyond the internal and external gear 16, is also fulcruined a le- Ver 19, which carries two friction-Wheels 2O 21, arranged in the same vertical plane and adapted to alternately engage a driving friction-wheel 22, fast upon the main drum-shaft 9 outside its journal-bearing in the side frame 2. The said wheels 20, 21, and 22 are provided at their peripheries with any suitable friction surfaces, preferably grooved, as shown, and the lever 19 preferably consists of a triangular body portion 23 and a forwardly-extending handle 241, said triangular body portion 23 carrying at its upper and lower angles short shafts 25 26, projecting inwardly toward the side frame of the ma- IOO chine and upon which the said friction-wheels 20 21 are mounted. also carry at their inner ends toothed pinions 27 28, adapted to rotate each with its adjacent friction-wheel and to engage one the interior and the other thc exterior gear-surface of the wheel 16. Furthermore, as each of said pinions 2'( and 28 lies in a radial line out from the center of the internal and external gear 16 it is obvious that said pinions are in permanent mesh with said internal and external gear. Therefore by swinging the lever 19 on its fulcrum 14 either of the wheels 2O 21 may be brought into frictional engagement with the driving-wheel 22 or both said wheels may be left in idle position, as desired, and the internal and external gear 16 (and auxiliary drum) correspondingly rotated in either direction or else left idle. For producing this motion or swinging of the lever 19 a link 29 Connects the end of the lever-handle 2st with a crank or crank-disk 30 upon the end of a shaft 31, transversely journaled in the auxiliary side frames 13 13, close to the bottom of the machine. At the opposite or operators side of the hoisting-engine this shaft 31 has a handle-lever 32, projecting' upward into convenient position and by means of which Said shaft 31 may be rocked to operate the lever 19. This controlling-lever 32 is preferably provided with catch means for locking it in any desired positionksuch, for instance, as the curved rack 33 on the frame 13 and a sliding plunger 34 upon the lever adapted to engage said rack.

To secure proper relation of the frictionwheels 2() 21 with the driving-wheel 22 where my improved device is put upon independent side frames, as shown in the drawings, the holes for the bolts 35 for holding said side frames to the skids 3 are elongated, as at 41, and the webs of the adjacent ends of each main side frame 2 and auxiliary side frame 13 are connected by a bolt 36, secured at one end to one frame and at the other end passing loosely through the other frame and having nuts on the opposite sides thereof, by means of which the frames can be drawn together, pushed apart, or locked in any position. In

the drawings I have shown the bolt 36 at-.

tached to the auxiliary frame 13, as at 37, and passing at its other end 38 loosely through the web of the main side frame 2 with nuts 39 40 on opposite sides thereof; but obviously these details might be varied so long as the frame-sections are adjustable with respect to each other.

Having thus described the invention, what I claim as new is- 1. In a hoisting-engine, a shaft, a driving friction-wheel fast on said shaft, a lever fulcrumed to swing in a plane parallel to said driving-wheel, friction-wheels mounted upon said lever and adapted to alternately engage said driving-wheel, a pinion upon each fric- Said short shafts25 26Y tion-wheel, and a wheel providinginterior and exterior surfaces adapted to be engaged one by each ofsaid pinions.
